Mibbu - javascript html5 game framework

I have just published initial release of Mibbu - my javascript microframework for fast game prototyping. To be honest - it is just set of functions and patterns I use always when I write my games. It is more a sandbox, starting place with basic tools, than a real framework (that's why I called it 'microframework'). It provides sprite animations, basic operations like movement or collisions, scrolling backgrounds and drawing on both - canvas or DOM. It uses DOM only when it is not possible to use Canvas (like in older IEs), but you can force it to do so with one single function (canvasOff()) - then it will be drawn with divs & imgs. It is the same mechanics I have used in OpenOdyssey or Janpu. I will try to write something more about using Mibbu later this week.
